Principles

stress is the force you apply, strain is the respond moduli is ???

There is a lot of plastic you can use, the recommended are HDPE, Delrin (a little bit of elesticity), Aluminium (speed and feeds are lower) using trocoidal? toolpath (circles)

Tslots for beams

pick

  • material
  • join system
  • frame system

Jens cycloid gear

othermill there is a “hole” aroud one shaft spalling when 2 pieces of same material rub together (friction)

sleeve bearing (selflubricant ?)
